Choosing an AQL

by Marcos

What I would like to know is why (AND in which occasions) some companies will choose to make the inspection based on only one AQL (1.5% for example) instead of 2 AQL (2.5% and 4% for example) or vice-versa.

4) Product defect levels can determine AQLs. If customer experience product defects, the supplier will tighten the AQL inspection to prevent escaping defects. If over time customer does not experience any issues then the supplier may loosen the AQL.

5) Without any guidelines or product history, a company may establish a baseline for the AQL depending on the feature or characteristic. After experience with customers and internal findings, the AQL can be adjusted appropriately.
